Further, as shown in FIG. 20, the ceiling surface 2a of the recess 2 is substantially horizontal, and a back surface 2c is formed in the vertical direction on the back side of the ceiling surface 2a. A lower inclined surface 2b is formed in an inclined shape.
That is, the inside of each recess 2 is formed in such a shape that the size is narrowed from the bottom to the top and the size is narrowed from the outside to the back side.

In such a structure, a procedure for attaching the cover 18 to the recess 2 will be described with reference to FIGS.
As shown in a perspective view of the main part in FIG. 12, an upper fixing bolt 10 and a lower fixing bolt 13 are arranged in the recess 2. That is, as described above, the nut 10b of the fixing upper bolt 10 is fastened to the upper bolt 4 and the lower bolt 5 penetrated through the back surface portion 1b of the toilet 1 with the deformed packing 11 and the washer 12 interposed therebetween, respectively. The upper bolt 10 extends coaxially with the upper bolt 4 and is disposed in the recess 2. Similarly, the nut portion 13b is fastened to the tip of the lower bolt 5 with a washer 12 interposed, and the fixing lower bolt 13 is fixed. It arrange | positions in the recessed part 2 in the state extended coaxially with the lower volt | bolt 5. FIG. As described above, the upper bolt 10 for fixing and the lower bolt 13 for fixing are extended, but the wall panel 3 of the toilet 1 is fixed to the wall panel 3 only by the upper bolt 4 and the lower bolt 5. 3 can sufficiently cope with the difference in thickness.

In this state, as shown in FIG. 12, the rubber tube 14 is put on the outer periphery of the lower fixing bolt 13 from the tip side. With the rubber tube 14 covered, as shown in FIG. 13, the ring portion 15 b of the cover bolt 15 is fitted into the outer periphery of the rubber tube 14, and the cover bolt 15 is attached to the fixing lower bolt 13 with the rubber tube 14. And the bolt portion 15a of the cover bolt 15 is set downward.
In this state, the top surface portion 21 of the cover 18 is brought into contact with the ceiling surface 2a of the recess 2, and the hook portion 22 of the cover is hooked on the back side of the upper fixing bolt 10, and the bottom surface portion 20 of the cover 18 is in this state. Is inserted into the recess 2 in a rotating manner. At this time, the bolt portion 15a of the cover bolt 15 passes through the guide groove 20b, and the bolt portion 15a of the cover bolt 15 enters the opening 20a.

With the bottom surface 20 side of the cover 18 fitted in the recess 2 as shown in FIG. 15, a temporary fixing tape 25 is stuck between the upper end side of the decorative wall surface 19 of the cover 18 and the toilet 1. The upper end of 18 is temporarily fixed to the toilet 1.
In this state, the nut 17 is screwed into the bolt portion 15a of the cover bolt 15 protruding downward from the opening 20a as shown in FIG. Then tighten the nut 17 with your hand as shown in FIG. At this time, the nut 17 is manually tightened while adjusting the front / rear position of the cover 18 through the opening 20a which is long in the front / rear direction. After the cover 18 is satisfactorily fixed in the recess 2, the temporary fixing tape 25 is peeled off, and the cover 18 mounting and fixing operation is completed.

When the nut 17 is tightened to the cover bolt 15, as shown in FIG. 20, an upward push-up force acts on the hook portion 22, so that the hook portion 22 is firmly fixed to the upper bolt 10 for fixing. The decorative wall surface portion 19 of the cover 18 does not shift outward. Further, since the top surface portion 21 of the cover is in contact with the ceiling surface 2a of the concave portion, the upper end of the decorative wall surface portion 19 of the cover 18 does not come off to the outside.
Further, since the decorative wall surface portion 19 is formed in a vertically curved shape, when the nut 17 is tightened, the decorative wall surface portion 19 is further curved outward, so that the cover 18 is recessed. The decorative wall surface portion 19 is substantially fixed to the side surface of the toilet 1 and is fixed well without being fitted into the inner wall 2.

  That is, when the cover 18 is fixed, the hooking portion 22 is locked to the fixing upper bolt 10 and a pressing force upward from the bottom surface portion 20 is applied by the tightening force of the nut 17 to obtain a strong fixed state. It is Moreover, since the concave portion 2 has a diameter-reduced shape toward the ceiling surface 2a and a diameter-reduced shape toward the back surface 2c, the cover 18 is extremely inside the concave portion 2 even if the nut 17 is tightened. The outer periphery of the cover 18 is firmly brought into contact with the inner wall surface of the recess 2 without being fitted, and a stronger fixed state of the cover 18 is obtained.

In the state where the cover 18 is fixed, the recess 2 is almost completely hidden (the lower side leaves a space for attaching the nut 17), and the fixing upper bolt 10 and the fixing bolt in the recess 2 are fixed. The lower bolt 13 and the cover bolt 15 are all concealed. Moreover, since the nut 17 is arranged at the most difficult position on the lower surface of the bottom surface portion 20, even if the toilet 1 is installed in a public facility, the cover 18 is not accidentally removed.
In addition, the upper inclined piece 19b of the cover 18 moves upward along the front inclined surface 2e of the recess 2, and the outer periphery of the cover 18 is firmly brought into contact with the inner peripheral wall of the recess 2, so that it is very refreshing. In this state, the cover 18 is firmly fixed. Moreover, when the nut 17 is tightened, the front / rear direction of the cover 18 can be adjusted well through the opening 20a so that the dimensional error of the toilet 1 can be absorbed well, and the cover 18 can be fixed in a clean state.

In this example, the opening 20a of the bottom surface portion 20 of the cover 18 has a notch shape having the guide groove 20b, but may be only the opening 20a not having the guide groove 20b.
Moreover, the upper bolt 10 for fixation and the lower bolt 13 for fixation should just be extended for fixation of the toilet bowl 1, and the bolt parts 10a and 13a do not need a screw | thread.
Further, the cover bolt 15 is fixed to the lower bolt 5 via the fixing lower bolt 13, but may be directly fixed to the lower bolt 5.

  In addition, in this example, although the structure which fixes the cover 18 to the recessed part 2 formed in the side surface of the toilet bowl 1 is illustrated, the cover attached to the recessed part formed in side surfaces, such as a urinal, a washbasin, or a sink, is also shown. The same fixing structure is adopted in the above, and the dimensional error of the sanitary ware is absorbed while the cover mounting position is adjusted well, so that the cover can be securely fixed to the sanitary ware.
